Adorno XIII 244
Substance/Hobbes/Adorno: according to the traditional scholastic definition, which was also explicitly stated in Descartes and Spinoza, substance is supposed to be quod nulla re indiget ad existendum, which does not need any other thing to be there.
This traditional concept of substance is fixed by Hobbes, but according to him it is related to the world of bodies. In materialistic terms, substance and matter are actually equated with all other philosophies.
On the other hand, Hobbes also holds on to the concept of accident,
Accident/Hobbes/Adorno: but the accidental is with him precisely the subjective affection.
The scholastic distinction is turned upside down, inasmuch as it is conceived in a broad sense that the mental, now to the accidental, and the being-in-itself of the bodies is now thought of as the substantial._____________Explanation of symbols: Roman numerals
